cmd/dist: mark linux/sparc64 as a broken port, remove incomplete map

The linux/sparc64 port is incomplete—it doesn't work, and it doesn't
have a builder. Now that dist supports broken ports, mark it as such.

The incomplete map was created to hide ports that aren't functional
from dist list output. Now that we have the broken port concept, it
seems largely redundant, so remove it for now.

For #56679.
Updates #28944.
